High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purity chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 4.43x10 Pa, what is its running pressure in torr? Express the pressure numerically in torr. ▸ View Available Hint(s) 4.43x10 Pa = IVE ΑΣΦΑ ? torr

The pressure in a constant volume thermometer is 0.800 x 102 Pa at 400 K and 0.600 x 105 Pa at 300 K. What is the temperature in K when the pressure is 0.500 x 105 Pa?

If the partial pressure of N2 is 3.25 x 105 and the partial pressure of Ne is 3.00 x 105 Pa in a given mixture what is the mole fraction of Ne(XNe)?

7. Unknown Pressure P Fluid of interest (Gas in most cases)- Po Ambient Fluid (Atmospheric pressure in most cases) Reference Fluid Density p (Liquid, e.g. water or mercury) Gage Pressure AP - P-Po - rgh In a manometer, the pressure p inside the apparatus is given as p = pex + pgh, where pex(po) is the external pressure, p is the mass density of the liquid in the tube, g = 9.806 m/s² is the acceleration of free fall, and h is the difference in heights of the liquid in the two sides of the tube. (The quantity pgh is the hydrostatic pressure exerted by a column of liquid. i) Suppose the liquid in the manometer is Hg, Pex is 760 torr, and the open side is 10.0 cm higher than the side connected to the sample. What is the pressure of the sample? The mass density of Hg at 25°C is 13.55 g/cm³. (Assume 25°C.)
